It is feasible to introduce the information on the sales and transactions at the sale terminals using WANs. It is also possible to centralize this information in a computer for processing or broadcasting purposes.

The central purchase and distribution center can supervise all the sale figures on a regular daily basis.
It is convenient for a business to centralize regional information. For example, auto-parts dealers can help locate rare-auto parts using a centralized computer file of inventory items. WANs enable such dealers to query centralized databases.
Organizations in advanced countries use WANs to help employee communications, store on long-distance phone calls and let writing, cut prices on the arrangement of written records, and overcome the time fail involved in the conventional means of extracting information between different branches.
